Breathable Loft Insulation
Posted 07 April 2016 - 11:04 AM
I'll get some pictures up soon of the detailing in my loft and create a new thread perhaps or add to my one from a new months ago. Will be interesting that's for sure as I've never seen so many timbers in a loft - we have basically a point in the middle and the roof is basically a pyramid.

It seems OK, yes. I've done it in my neighbours house, took around ten minutes for the two of us to cut up bits of waste pipe we had around and stuff it between the sarking felt, the same way as the Easyvent system fits. Fixed his loft condensation problems every bit as well as all the extra soffit vents I fitted.

I may well do the pipe trick then and maximise the insulation up to the eaves
We've got a damp proof membrane in the roof under the tiles as relatively new build, we also have no vents fitted in the soffits but I can see daylight from the eaves, again will take pictures and get some opinions on here before I take the plunge with all the insulation detailing

Pictures will be forthcoming when I can get my backside up in the loft once I've been to Wickes to get some suitable boarding to stand/lie on for all the work I'll be doing.

I did consider a warm roof made of I joists and OSB top and bottom and cellulose poured down the gap ?

There are people other than installers with blowers. MBC fit cellulose insulation themselves, and I'm guessing they either own or hire a blower. I'm seeing them in the next week or two, at their new Gloucester factory, so I'll try and remember to ask whether they own the blower or hire it, and if the latter where they hire it from.

Edited to add: This listing is for one that does definitely blow cellulose: http://www.ebay.co.u...yKq3ugEhZWRsSlw

No idea if good or bad but seems like a lot to blow stuff in for a day.

Last time I checked the cost for the DIY install, materials only, Warmcell was around £40/m3, if that's any help. Generally a thick layer of Warmcell (or similar) costs less than other forms of fitted insulation, because it's so much quicker to install.
40m3 should be around £1600 (at retail prices) for materials, plus the labour and blower cost. I've no doubt the wholesale price of the stuff is between 1/2 and 2/3rds the retail price, though.
